We had a short discussion on this within the MPICH group. We believe

mpich2-1.3, you should be able to configure it in by default.
Hi Pavan,
What's the conclusion on this? Should I enable checkpointing by default?
(Context: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=555714)
There will be some overhead in enabling this, but I think that should be
minimal. I'm checking with our developer who worked on this. I'll get
back to you.
